lIMPROVEMENT IN DUMPING APPARATUS.

Specification forming part of -Letters Patent No. 514,4 l2, dated September 27, 1864.

.To all whom .it'may concern.-

Royal Mine, in the county of Houghton and State of Michigan, have invented a new and Improved Dumping Apparatus; and I do hereby declare that the following is a full,

clear, and exact description thereof, which will `enable those skilled in the art to make and Au se the same, reference being had to the accompanying drawings, foi ming part of this specitication,in whichf Figure 1 is a side` sectional elevation of my invention. Fig. 2 is a plan view cf the same.

Similar letters ofrei'erence indicate'corresponding parts.

This invention pertains to the class of devices that are employed for elevatin'gores,

minerals, earthy matters,and other substances from mines, Wells, excavations, and subter ranean places of all kinds.

A represents the 'upper termination of the usual railroadtrack or skip-road rising from the mouth of a mine. A A2 are extensionrails attached to A, as shown. .B is the skip or dumping car in which the ore or other substance to be moved is carried. The car B is provided with flanged wheels tokeep itupon the track in the usual manner. The car B is propelled or drawn by means of a swinging bail, C, which is pivoted by ears c c to the sides of thc car, as shown. Above the mouth of the mine there is a frame-work, D, across the upper part of which is journaled a suitable rope-wheel, E, over which runs the lifting-rope F, by mea-ns of which the car B is elevated, said rope being attached to the bail C, as shown. The wheel Vll maybe so arranged over the mouth of the mine thatv when stretched it will not touch the track, thus vleaving the latter always free and unobstructed for theintroduction of timbers into the mine. At a "certain distance above the mouth of the mine, where it is desirable to cause the car to dump'its load, I cut horizontal recesses b b on the inside of the track front wheels arrive at the recesses b 11 will pass along horizontally on the inner edges of said recesses, but the bail C willcon I ltinue to move'upward'on the samepath as B e it knownthat l,FEANK F1cHT,'of .Isle

before, and while the front of the car passes h irizontallyalong the recesses b the bailwill s .vin g over the rear of the car and lift up the roar part thereof, thus inverting, or nearly invertin g, the car, as shown in red, Fig. 1,) and cause the contents thereof to be discharged. In this position of the car. or skip the front wheels thereof will have passed to the extreme lai-mit of the recesses b b into pockets b at the end of the recesses, While .the hind wheels of the-car, now inverted, Willride upon and be guided' by the upper rails, A', and the front wheels will run between the rails A A2. (See red lines, Fig. 1.)

Arranged upon a suitable frame, D, directly under the recesses b b, is a friction-roller or a set of frictionwheels, G, the use of which is to form a bearing surface for the front edge of the car to strike against when it is inverted, to prevent 'the front wheels vof the car from during the dumping operation, or during the downwardst'artin g of the'car. (See red lines, Fig. l.)

The skip or car B is to be so made and depth, that when the loaded car rises it Iwill by its own action pass with its front. wheels into the recesses b, while the body inverts' itself and the hind wheels mount the track A above the recesses b, as before described,- and when the rope is lowered the rear of the car will, by'its own gravity, return to its original position, and the hind wheels will run down the track A', below the recesses b b, onto the track yA, and the weight of the hinder part of the car will be sucient to draw thc front wheels out ot' their recesses b b, and cause. the descent of the skip or car into the mine for a new load.

My improvement thus constitutes a selfacting dumping apparatus, simple in con-A mechanic as various circumstances may require.

becoming displaced or thrown o the track y hung, and the recesses b b are to be of such a What I claim as new, and desire to secure substantially as herein shown and described. by Letters Patent, is- 3. The employment of the skip 0r car B in 1. The combination 0f the recesses b b combination with the above-named parts, subwith the rails A A A2, or vtheir equivastantiallyas herein shown lmd described. lents, substantially as herein shown and de- FRANK FIGHT. scribed.

2. The employment of the wheels G, in FRANK HARTMAN, combination with The above-named parts, N. H. HAAN.
